To aZZ 'whom z't may oonoern:

Be it known thatV I, WALTER 'W. SOHMIDT, a citizen of the United States, residing at Fond du Lao, in the county of Fond du Lac and State of Wisconsin, have invented new and useful Improvements in Looking Devices, of which the following is a speoification.

An object of the invention is to provide a looking device for use in effeotually seouring a closure or the like to the frame thereof.

The invention oontemplates, among other features, the provision of a looking device that is particularly adapted for use in conjunction with storm and screen doors and especially in connection with those kinds of doors known as combination storm and screen doors.

To this end use is made of a suitable base orvplate upon which is arranged to rotate a looking element so constructed and designed that portions thereof will extend beneath a ledge upon a closure and also project into a recess in the closure, the looking element being mounted to rotate upon the plate, with said plate suitably Secured to the casing which is to be associated with the closure.

Still further embodiments of the invention reside in a looking device which consists of few and simple parts that can be cheaply manufactured and which cannot readily get out of order.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constitutng a part of this specification, in which similar characters of referenoe denote oorrespondingparts in all the views, and in which:

Figure 1 is a fragmentary elevation showing my devicev applied to a closure held in locked relation to its casing; Fig. 2 is a horizontal sectional view taken on the line 2-2 in Fig. 1; Fig. 3 is a vertical transverse sectional view taken on the line 3-3 in Fig. 1; and Fig. l'is a perspective view ofthe locking element.

Referring more particularly to the views, I disclose a oasing 10 and a closure 11 for said casing, the closure 11 being provided With a projeoting ledge 12 and having an underout recess 13 immediately beneath the ledge 12, said recess being formed in an edge 14 of the closure. The closure 11 is adapted to bear against the edge 111 of the oasing 10 as shown, and the oasing is preferably provided with a depression 15 in which is fitted and securely arranged a plate 16 having a .l'ising4 rim 17 adapted to receive therethrough suitable nails, sorews ,or other securing members 18 whereby to rigdly secure the plate in the depression so that the edge of the rim will fit substantially fiush with the face of the closure. The looking element is designated by the numeral 19 and is preferably arranged to turn upon the plate and within the rim by having a screw 20 passing loosely through the looking element, the.

plate, and threaded into the body of the casmg.

The looking element consists, more particularly, of a single piece of material forming an upstanding and elongated handle 21 and lateral projections 22 preferably having inclined faces 23 Whereby said projections will be of a substantially wedge-shaped construction, the projeotions extending in opposite directions with respect to the handle and adapted to pass beneath the ledge 12 When the handle 21 is aotuated to rotate the looking element upon the plate, said projections, furthermore, being adapted to extend into the reoess 13 formed in the closure adjacent the ledge 12 thereof.

When the looking element is in unlocked relation to the closure an edge 23 thereof will lie parallel to the edge of the ledge and when a quarter turn is given to the looking element, it will be seen that one of the projections will pass beneath the ledge and extend into the recess 13, a plurality of the projections 22 being provided to form a part of the looking element in order to adapt the fastening device to right and left hand sides of oasings and the olosures thereof.

From the foregoing description it will be clearly seen that the fastening device described consists of fewT and simple parts and primarily involves merely a plate forming a seat for a revoluble looking element lying within the plate, with suitable screws, nails or other fastening members for seouring the plate to a casing or the like and for revolubly supporting the looking element upon the plate.

Having thus described my invention, I claim:

In oombination, a rectangular closure having a recess formed in one edge, a casing abutting the recessed edge of the closure and also having a shoulder contaoting with one side of the closure, said casing adjacent the recess being previded With a depresson, a plate toward its outer extremity and ar- 10 loeking element seated in the depressio-n ranged to engage one Wall of the recess. comprising a pair' of'alining'projections, a In testinony Whereof I affiX my signature handle extending at right angles to thevpro-I Y in presence of tWo Witnesses.

'1 jections and a screw passing through said WALTER W SGHMIDT element at the juncture of the projectons andhandle through said plate and into said Witnesses:

casing, each of said projections-havingits" L. J. S'GHMIDT, under surface inclining away from ,said GERTRUDE A. GRABE.
